Will FDA Liver Warning and Newborn Screening Expansion Change Sarepta Therapeutics' (SRPT) Risk‑Reward Narrative?

• Sarepta Therapeutics recently executed a convertible notes exchange to ease near-term refinancing pressure and extend its cash runway, while the FDA updated the label for its gene therapy ELEVIDYS with a boxed warning for acute liver injury and restricted use to ambulatory Duchenne muscular dystrophy patients, and also cleared a new ENDEAVOR study cohort to test an enhanced immunosuppressive regimen.

If this regimen meaningfully reduces serious liver events while preserving efficacy, it could support physician confidence and potentially reopen the discussion on treating broader Duchenne populations over time, though the path and timing remain uncertain.

Yet, investors should also be aware that if acute liver events were to worsen or lead to stricter restrictions, the impact on ELEVIDYS demand and Sarepta’s earnings could...
